Unexpected output when looping over empty objects

[planeiii-te]

Describe the bug
Looping over an empty object still returns a list of elements somehow.

Version of yq: 4.33.1
Operating system: mac
Installed via: homebrew

Input Yaml
meh.yml:

other: thing
labels: {}

Command
The command you ran:

yq '.labels[] | select(tag != "!!str") | ">" + key + "< " + (key | line) + " " + tag' meh.yaml

Actual behavior

Consistently outputs 0 as the line number. The key is the empty string. This doesn't change even when labels is much lower down in the file.

>< 0 !!null

Expected behavior

# no output
